A recently published study from Chalmers University of Technology has gone into the details on material issues for CSP. The main conclusion is that CSP does indeed seem to be largely unrestricted, viewing the material requirements compared to the global reserves. In theory, enough solar plants could be built to cover -- at the very least -- five times the current global electricity demand.

However, the report also highlights some issues that are likely to pose challenges to the industry. The main point of concern is that silver, today extensively used for reflecting surfaces, will most likely be in short supply in the coming decades even without demand from a booming CSP industry. CSP mirror manufacturers might have to look at other reflective surface materials, such as aluminium, to secure cost competitiveness.
